Abstract:
OBJECTIVE:To evaluate the clinical value of heterogeneous acellular dermalmatrix with autologous bone meal in open tympanoplasty.
METHOD:Twenty-eight cases (30 ears) with middle ear cholesteatoma were trea- ted by open tympanoplasty and repaired by heterogeneous acellular dermalmatrix autologous bone meal on study team. Twenty-two cases (22 ears) with middle ear cholesteatoma were treated by open tympanoplasty on control team. All patients were followed up for 12 to 18 months and assessed the fuction postoperatively.
RESULT:The re- construction of external auditory canal structure is close to normal, and no narrow happens on study team. The rate of dry ear was about 90%. All cases had no recurrence of cholesteatoma.
CONCLUSION:Application of decellu- larized dermal matrix with autologous bone meal can rise early to cover the wound, promote wound healing and to reduce the external auditory canal, reduce the effect of granulation and scar formation. It is a kind of method of repair to be promoted.
